What is “normal” body temperature?
“Normal” body temperature varies from person to person, changes according to time of
day and body location. Hot or cold baths, physical exercise, smoking and drinking, hot
or cold drinks may change body temperature b one degree or more.
The following table shows the temperature ranges:

The thermometer is designed to measure the temperature in the forehead, in approx..
between the end of eyebrow and the hairline. It is important to know that the thermal
characteristics of each measurement body location – forehead, axillar, oral or rectal –
are unique. The variance in temperature measurement in different body locations is
due to the human body and not the thermometer.
It is recommend to measure the body temperature when healthy to establish the
specific normal temperature.
PRECAUTIONS FOR USE
1. The device can be used by all persons, including children, elderly person &
Patient. Handicapped persons and Children need assistance by another person to
use the device.
2. Use of the device is not intended to be a substitute for consultation with your
physician.
3. Disregarding the information given in this instruction manual is considered to be
abnormal use.
4. The device is for indoor use only. Please do not use the device under a noisy

dust. The performance of the unit may be degraded.
8. Normally speaking, body temperatures in the morning (lower) will be different from
that in the afternoon (higher). So, please measure your body temperature in the
same place and at the same time of day.

MEASURING GUIDELINES
1. Measurement location is the area between the end of eyebrow and the hairline.
2. Do not place the thermometer on scarred tissue compromised by skin disorder,
open sores or abrasions and patients in trauma.
3. Temperature readings are affected by many factors including exercise and drinking
prior to taking a reading.
4. Consult your physician when using drug therapies that may raise the local skin
temperature in the forehead; this may lead to incorrect reading.

4/11
5. If the thermometer has been stored at a cold temperature, allow the unit to warm
naturally to room temperature before using.
6. Performance of the device may be degraded if operated or stored outside stated
temperature and humidity ranges.
OPERATION
Before measuring:
1. Sweat will affect the reading result on the forehead, so please make sure your
forehead is clean before measurement.
2. Move the hair aside from the measurement location and apply the probe to the bare
skin.
Taking temperature
1. Press on/off button to turn on the unit.
2. The LCD window will display full segments for approx.. 1 second.
3. Then, the last measured value will be shown on the LCD screen with “M” icon
(memory).
4. Finally, you will see “Ok” on the LCD screen, it means the thermometer is ready for
measurement.
5. Place the probe sensor in the area between the end of eyebrow and the hairline.
6. Gently press and hold it against the measurement location to ensure good contact
with the skin is maintained.
Correct placing and good contact with the skin ensure reliable readouts.
Make sure the thermometer and the patient do not move while measurement
is in progress.
7. When you will hear a long beeping sound, it means the measurement is finished.
8. Remove the probe sensor and the LCD screen will display the measured value.
9. If the measured value is over 37.8℃(100 ℉), six consecutive beeps will be heard
to indicate fever alarm.
10.For re-measurement, please wait until you see ” Ok” on the LCD screen.
11.After measurement, if no button is pressed, the thermometer will enter standby
mode after 1 minute. Under this mode, current room temperature and the icon
“ ” will be shown on the LCD screen. If you want to switch to Forehead mode,
please press on/off button again.
12.To turn off the thermometer under any mode, press the on/off button.
Do not make any measurement until you see “Ok” on the LCD screen. If you
measure the body temperature before seeing “Ok” on the LCD screen, the
thermometer won’t detect the temperature.

5/11
Make sure that the probe completely touches the skin as below.
For all types of thermometers, slight temperature variations can happen. Therefore,
it is recommended to take several readings (removing the thermometer from the
forehead between each measurement) and take the highest one into account.

and d is the recommended separation

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the FT7122 is used
exceeds the applicable RF compliance level above, the FT7122 should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
the FT7122.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between
portable and mobile RF communications equipment and the FT7122
The FT7122 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the FT7122 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the FT7122 as recommended below, according to the maximum output power of the communications
equipment.

is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
EXAMPLE 1 As indicated in Table 6 of IEC60601-1-2:2007 for ME EQUIPMENT, a
typical cell phone with a maximum output of 2 W yields d=3,3 m at an IMMUNITY
